현재 국내 일정규모 이상 댐들에 대해서는 "안전점검 및 정밀안전진단 세부지침(댐)" 기준에 따라 정밀안전진단을 수행하고 있다. 하지만 여러 평가 기준 중 수문학적 안전성 평가는 가능최대홍수량(Probable Maximum Flood, PMF)에 대한 기존 댐 안전성을 평가하는 것으로 대부분의 농업용저수지에 대해서는 적용성이 많이 떨어진다. 따라서 본 연구에서는 계수화 모델과 AHP 기법을 통해 다각적 위험요인을 고려한 농업용저수지의 수문학적 안전성을 재평가하고자 한다. 이를 위하여 농업용저수지의 다양한 인자를 반영하기 위한 수문학적 안전성 상 하위 평가항목을 선정하여 계수화 모델을 개발하였다. 평가항목 별 지표 점수의 총합을 산출한 후 전문가 집단의 응답에 대한 검증절차를 실시하였고, 평가항목의 가중치를 산정하여 최종적으로 다각적 위험요인을 고려한 농업용저수지의 수문학적 안전성 평가를 위한 실용계수를 산정하였다. 본 연구 결과 기존 평가기준은 댐의 가능최대홍수량에 대한 수문학적 안전성을 평가하는 기준으로 대부분의 농업용저수지에 대해서는 홍수방어능 부족에 따른 제체의 월류로 저수지의 파괴위험성이 큰 것으로 분류되었다. 그리고 가능최대홍수량에 대한 여유고 기준을 만족하는 저수지에 대해서는 댐의 형식 및 상태별 여유고에 대한 평가만으로 필댐을 평가하는 것으로 나타났다.

From a viewpoint of human factors, automated highway systems(AHS) can be defined as one of the newly developing human-machine systems that consist of humans(drivers and operators), machines(vehicles and facilities), and environments(roads and roadside environments). AHS will require a changed vehicle control process and driver-vehicle interface(DVI) comparing with conventional driving. This study introduces a fixed-based AHS simulator and provides questionnaire-based human factors evaluation results after three kinds of automated driving speed experiences in terms of road configuration, operation policies, information devices, and overall AHS use. In the simulator, the "shared space-at-grade" concept-based road configuration was virtually implemented on a portion of the Kyungbu highway in Korea, and heads-up display(HUD), AHS information display, and variable message signs(VMS) were installed for appropriate AHS DVI implementation. As the results, the subjects expressed positive opinions on the implemented road configuration, operation policies, and the overall use of AHS. The results of this study would be helpful in developing the road configuration and DVI design guideline as the basic human factors research for the future implementation of AHS.

In order to attract foreign tourists, it is important to understand what factors on domestic tour spots are critically considered and how they are evaluated after visit. However, most of the researches on tour business have collected information from tourists through survey on a small number of tourists, which leads to inaccurate and biased conclusion. In this paper, we suggest a data-driven methodology to figure out tourists' satisfaction factors and estimate sentiment scores on them. To do so, we collected review comments data from popular web site. Latent dirichlet allocation is employed to extract key factors and elastic net is used to estimate sentiment scores. Then, an aggregated evaluation score is generated by combining the factors and the sentiment scores per topics. Our proposed method can be used to recommend travel schedules with themes and discover new spots.

Purpose : This study aimed to identify the prevalence and risk factors of cognitive impairment in survivors discharged from the intensive care unit (ICU). Methods : This secondary analysis study utilized data from a multicenter prospective cohort of post-ICU patients. We analyzed the data of 175 patients enrolled in the primary cohort who completed the cognitive function evaluation three months after ICU discharge. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA) scale. The cut-off points for cognitive impairment were < 23 for face-to-face evaluation and < 18 for telephone evaluation. Results : The prevalence of cognitive impairment three months after ICU discharge was 32.6%. Significant risk factors for cognitive impairment were age ≥ 60 years (OR=10.52, 95% CI=3.65~30.33, p<.001), education < high school graduation (OR=2.53, 95% CI=1.07~6.01, p=.035), unplanned ICU admission (OR=4.01, 95% CI=1.45-11.14, p=.008), and delirium in the ICU (OR=4.33, 95% CI=1.08-17.23, p=.038). Conclusion : ICU nurses should use preemptive strategies to reduce post-ICU cognitive impairment of patients with risk factors. It is necessary to frequently assess and detect early delirium in critically ill patients, while attempting various non-pharmacological interventions.

MAUT and AHP are widely used for quantification of subjective judgements in various fields of decision making. This study focuses on the introduction and application of MAUT/AHP method which is a hybrid of MAUT and AHP techniques in R&D project priority setting. This hybrid model can clarify each factors' contribution using MAUT method and can reduce the number of pairwise comparisons of AHP method. This study applies AMUT/AHP method to the evaluation of R&D projects in a Government - funded research institute. To evaluate R&D projects, six evaluation factors are derived. SMART(Simple MultiAttribute Rating Technique) and DVM(Difference Value Measurement ) out of many MAUT methods are used to design the utility function ad AHP is used to allocate the weights among evaluation factors. The major findings of this study can be summarized as follows. First, the SMART/AHP and the DVM/AHP have the same results with the SMART and the DVM, and they are different results with AHP. It is very hard to decide which one is better. Second, MAUT/AHP's strength is analyzed. MAUT reflects utility values of evaluators to alternatives and AHP results objective and consistent weights of factors through pariwise comparisons. Third, its possible application fields are proposed. It is applicable to subjective decision making problems with high complexity and inter-independent factors.

The purpose of this study was to investigate the differences in restaurant employees' perceptions regarding the importance of specific evaluation factors when judging wine quality. To analyze the data of the study, we employed descriptive statistical analyses, t-tests and ANOVA. The findings of the study are as follows: First, the importance and influence of the palate on evaluating wine quality attained the highest score. The nose, appearance, and 'others' also earned significant points in the respective order. Second, when we examined the servers' differences in perception about the importance of each factors on evaluating wine quality, significant distinctions were shown among males and females, and those in their 20's and 30's. Third, employees' perception about the importance of each factors also showed clear differences with regards to the wine servers' gender and experience with wine. Finally, we hope the results of this study provide useful information for the hotel restaurants and other food & beverage businesses. Specifically, this research may be used to establish helpful criteria for recommending and presenting the suitable wine items based on the customer's individual tastes and preferences.

Industrial accidents have been consistently increased in terms of medical costs, lost work days, and incidence rates every year in Korea. Since the infrastructure of the industry changed shifts rapidly from 1980s in the developing countries such as South Korea, the nature and magnitude of the industrial accidents have also undergone a major shift. The situation is especially severe in small-to-medium sized industry(SMI). This article reports the development of a systematic evaluation system of risk factors specifically for the SMIs. The new approach introduced by this article is geared to the systematic identification and evaluation of the injuries from power press machines using the Analytic Hierarchy Process with the key evaluation data generated and evaluated by the employees on site. A total of 21 companies was studied and surveyed using the hierarchical structures of the cause-effect relationship of the mechanical injuries and their countermeasures. For the relative weighting of each risk factor, separate questionnaire survey was conducted for the selected workers from each company who had worked for more than 10 years in press work. Most participants (48 out of 62) replied that human attributes were the most significant factors for mechanical injuries fellowed by administration, machine, and work environment factors. The result also showed that the self-motivated risk assessment and safety enhancement activities would be an effective and efficient way of managing the risk factors in the SMIs.
